This phase IIa trial studies the side effects of atezolizumab when given together with paclitaxel, trastuzumab, and pertuzumab and to see how well it works in treating patients with HER2 positive breast cancer that has come back at or near the same place as the original (primary) tumor (locally recurrent), has spread to other places in the body (metastatic), or cannot be removed by surgery. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Trastuzumab is a form of targeted therapy because it works by attaching itself to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors. When trastuzumab attaches to HER2 receptors, the signals that tell the cells to grow are blocked and the cancer cell may be marked for destruction by the body's immune system. Pertuzumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving atezolizumab, paclitaxel, trastuzumab, and pertuzumab may work better in treating patients with HER2 positive breast cancer.

This randomized phase II trial studies how well olaparib with or without atezolizumab work in treating patients with non-HER2-positive breast cancer that has spread from its original site of growth to nearby tissues or lymph nodes and is not amenable to surgical resection (locally advanced unresectable) or has spread to other places in the body (metastatic). Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body’s immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. It is not known whether giving olaparib with or without atezolizumab will work better in patients with non-HER2-positive breast cancer.

This is a Phase 1 open-label, multicenter study of the safety and tolerability, immunogenic effects, antitumor activity, and pharmacodynamics of SQZ-PBMC-HPV as monotherapy and in combination with atezolizumab in HLA-A*02+ patients with recurrent, locally advanced or metastatic human papillomavirus strain 16 positive (HPV16+) solid tumors.
